Does he think the City is going to enjoy a boost in its sales taxs. Hardly. Facebook makes it money from advertising on the internet. No sales taxes on those revenues.
Then you read about neighbors complaining about Facebook and all the problems being around them.
The Sun campus is a bit over 1 million sq. feet. Facebook crams its workers into "cubby holes". They might be able to squeeze 1 worker / 100 square feet. That would mean 10,000 more workers to Menlo Park. Maybe that's exaggerating a bit, but 1 worker / 200 square feet, would mean 5,000 more workers to Menlo Park -- very doable.
Then talking with some Facebook people, they are looking not only for the existing 1 million sq. feet, but expect to need 2 million plus square feet within a couple of years.
Let Facebook move to the green pastures of San Jose with all its masses.
Come on Rojas and Dave Johnson, get with it.
